Van Ostern held an event with family, friends and supporters in Concord where he laid out his plans and motivations for his campaign.

Van Ostern also shared what his main focus would be if he was elected.

"The heart of moving us forward as a state is a strong work force and high quality of life,” Van Ostern said. “Now, obviously, we have an emergency in the heroin/opioid crisis. That threatens not just people who are dying every day, but the quality of life that we have in New Hampshire, and affects all of us."

Van Ostern said as governor, he will also focus on education as well as bringing younger people to the state and keeping them here.

Steve Marchand and Mark Connolly are also running for the Democratic ticket.
